INVENTOR. BENJAMIN RMIRANT BY 1 ATTORNEY F FFl@.

BENJAMIN AMIRANT, OF CHICAGO, ILLINOIS.

rnnss,

Application filed November 22, 1915.

To all whom it may concern Be it known that I, BENJAMIN AMIRANT, asubject of the King of Italy, and a resident of Chicago, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Presses Adaptcd to Express Juice from Grapes, Apples,

and other Substances.

The device embodying this invention relates to that class or kind ofpresses in which the juice of grapes and other articles is obtainedtherefrom, by pressure.

I find that a great part of the juice in grapes is forced out uponmoderate pressure being applied to a mass, thereof, and that greaterpressure is required to extract additional juice therefrom; and Idesire, in the device embodying this invention, a machine in which aquantity of grapes may be deposited, pressure may be applied thereto anda large portion of the juice therein be rapidly obtained therefrom, andthereafter additional and greater pressure may be applied and anadditional quantity of the juice contained therein may be obtained.

Particular objects of the invention are to obtain means whereby, uponthe change of position of a determined lever, like movement and forceapplied to said lever will obtain a difference in pressure on thecontents of the tub of the device: to obtain a device from which thepressed contents of said tub may be readily removed: to obtain a devicein which the operative pressure producing lever may be continuouslymoved in a determined direction to obtain a determined pressure, andcontinuously moved in the opposite direction to lessen said pressure;and a device in which said lever may be moved to and fro, tocontinuously increase or continuously lessen said pressure: to obtain adevice inwhich the required changes of position'of the operative partswhich determine whether greater or lesser pressure will result from ameasured movement of the determined lever are readily understood, andeasily made.

In reducing to practice this invention 1 have embodied the same in thedevice which is illustrated in the drawings accom- Specification ofLetters Patent.

panying and forming a part hereof, and in which;

Figure 1, is a vertical sectional view of said device on line ll of Fig.2, viewed in the direction indicated by the arrows. Fig. 2, is a topplan view of the device. Fig. 3, is a perspective of a movable memberwhich is actuable by a lever. Fig. 4, is a perspective of a movablemember cooperating with the member illustrated in Fig. 3, and adapted tofunction as a dog or pawl. Fig. 5, is a perspective of an additionalmovable member adapted to be actuated by a lever and cooperativelyattachable to the member illustrated in Fig. 3. Fig. 6, is a perspectiveof a retaining member of the device. Fig. 7, is a vertical section, online 7-7 of Fig. 3, (viewed in the direction indicated by the arrows),of the member which is illustrated in said Fig. 3, and an elevation of arotatable nut on which said member is pivotally mounted. And Fig. 8, isa perspective of a head member provided with an abutment on which themember illustrated in Fig. 5 may be pivotally mounted.

A reference character applied to designate a given part indicates saidpart throughout the several figures wherever the same appears.

A is a table forming a base, and is provided with an annular runway at,spout a and legs B.

C is a vertical shaft which is screw threaded at its upper end, and isrigidly secured in table A. The manner in which said shaft C is secured,(as illustrated in Fig. 1), is by means of the hub D, key E, and nut F.Nut F fits over the lower end of said shaft D, (which is screw threaded)and by turning the said nut tightly to place the shoulder G is broughtfirmly against the upper face of said table A.

The tub of the device comprises the slats H, and straps I, which areturned over at their ends to obtain eyelets or apertures in which thepins j (see Fig. 2), and removable pins'J fit. Slats H are illustratedas attached to the straps I (by bolts K), to obtain a spaced relationbetween them, and through the space between said slats, (lettered L inFigs. 1 and 2) the juice'extracted from the contents of the tub flowsinto the annular groove 0; and is discharged from said groove to spout mM represents pressure board of the device and m, blocks placed thereon.

N is a head or collar which is provided with aperture n, in which shaft0 loosely fits, with the abutment n having the hole or aperture n?therein and the annular recess N (see Fig. 8).

0 is a movable member provided with the aperture 0 (see Fig. 5), and therecess 0 at the upper end of said aperture, and with the apertures O andO Said member 0 is pivotally mounted on head or collar N, when the pinor bolt 0 is inserted in the apertures O and n with the head of saidbolt in said recess 0 P is a nut, the screw threads whereof fit thescrew threads on .shaft 0, so that by the turning of said nut inopposite directions it is :moved up and down on said shaft. Nut P isprovided with an annular flange "P, which fits into therecess N of heador collar N, permitting. rotation of the nut without rotation of saidhead or collar and transmitting the upward and downward movement of saidnut to said collar. Said nut P is also provided with the annular flange29 having apertures 19*. Q is a movable member which is pro vided'withthe apertures g, 9 Q2, and g (see Fig. Aperture 9 fits loosely on orover the upper end of nut P so that said member Q is pivotally mountedon said nut, while resting on flange p.

R are bolts which fit loosely in holes Q and are provided with the heads1", to determine how far said bolts shall project beyond the lower faceof said member Q; and

said projecting'lower ends of bolts R are beveled, as is wellillustrated in Figs. 4 and 7. The movable member. Q being pivotallymounted-on nut P, the apertures q ,-in said member register withapertures p in flange p of said nut, and the projecting lower ends ofsaid bolts R extend into (fitting loosely therein), said holes 9 WVhentwo, (2) of said bolts R are inserted in said member Q and l l bP in thmanner which is illustrated in full lines in Fig. 7 said member "and nutare tied or locked together so,that 1 pivotal movement of said member Qproducescorresponding movement of said nut P- When the bolt R which isillustrated as the left hand one in Fig.7, is inserted so that thebevelededge r thereof is inthe position indicated by broken lines insaid Fig.7, movement of memberQ in one direction (to the left) willproducecorrespending movement in nut P, while move- 1Inentofjsai'dmember Q in the opposite dimotion will simply cause said bolts R to bemoved up out of apertures 10 by the slotted aperture Q2 of member Q andaperture O of member 0 register, and T (Figs. 1 and '2) is a bolt whichwhen put into place, extends through said apertures. When bolt T isinserted in said apertures reciprocatory pivotal movement of member 0produces reciprocatory movement of member Q, but the angle of movementof said member Q will be considerably less than the angle of movement ofsaid member 0. On

.the removal of bolt T and the placing of the lever S and said member Qwill, of course, correspond. Much less movement of the nut P is obtainedby a given movement of lever S, when said lever is in aperture O ofmember 0, than when in aperture g of member Q, but with correspondmggain of pressure to the pressure board M thereunder.

U is a retaining device (see Fig. 6,) which is secured to the under sideof member Q by bolts 11, (Fig. 1).

To operate the device I deem it advisable to first place the bolts R inposition as illustrated in Fig. 7, and lever S in aperture y to thenfill the tub with the material to be subjected to pressure; then placepressure .board M, blocks on and nut P on shaft C by continuously movinglever S, in a given direction; that is, the party operating the devicecan walk around it, and continuously force the nut P and pressure boardM downward. When the forcing of the said lever S continuously in a givendirection becomes somewhat difiicult, said pins R are placed as is theright hand one of the pins illustrated in Fig. 7, and said lever is thenmoved to and fro. When the force required to move said lever S being inaperture q is burdensome said lever placed in aperture- .0 of member 0,pins 0 and T are dropped into their respective apertures and lever S isagain moved to and fro thereby moving member Oto and fro, said member 0actuating member Q to and fro by means of the bolt T.

I claim I In a press, provided with a stationary, vertical, screw;threaded shaft, and a pressure board, operative means to move said boardcomprising a head, longitudinally llO ber provided With spaced aperturesadapted to register with the apertures in said flange, pivotally mountedconcentric to said nut and bolts loosely mounted in said apertures, saidbolts beveled on the lower ends thereof and adapted When oppositelyplaced, to join said movable member and said nut and when similarlyplaced to join said member and said nut when said member is moved in onedirection.
